If you drop a feather and a coin at the same time in a tube filled with air which will reach the bottom of the tube first?

The coin.

The reason is because the tube is filled with air. Air caused air resistance. The feather has much greater air resistance than the coin, so the air will hold the feather up for a bit while the coin will likely turn on it's side and fall quickly.

Now, if it was a tube without air (a vacuum), they would fall at the same rate because there is no air resistance. Gravity acts on the same objects in the same way, essentially. The weight of the two objects is different, so gravity actually puts an amount of force on them differently. However, because gravity does this gravity accelerates both objects at equal speeds.
